SELECT - Calculation of Risk

Components of Risk

The inhalation, ingestion and dermal exposures are multiplied by the carcinogenic potency factors for each of these pathways and integrated over the exposure duration specified in "Calculation Options" under the Risk main menu selection (see below.) These durations are currently set to 14 years for an individual and 70 years for a population.



Graph of Risk wrt Target

Hypothetical risks via the three exposure routes are summed and plotted. The value and year of the maximum likely population or individual risk are recorded for each selected remediation strategy.



Max Risk per Strategy

After two or more strategies have been simulated, a graph is available showing comparative maximum risk over time and the cost of each strategy. The risks are plotted with respect to a desired target risk that is specified in "Calculation Options" under the Risk main menu selection (see below.)



Risk Notes

The "Secondary Risks" button on the Individual and Population Risk graphs displays comparative data on the risk of cancer caused by exposure to the same contaminant in sources other than inhabitation of the contaminated site.
